Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding bicycle, various devices for forming the folding bicycle, and a storage device.

[0002]

2. Description of the Related Art In a conventional folding bicycle, hinges, joint shafts, etc. are arranged on a frame constituting the bicycle, and mainly, FIG. 11 (a) conventional method (1) and FIG. 11 (b) conventional method (2). Based on the two types of folding methods shown in Fig. 2, fixing metal fittings are arranged on these so that the conventional riding and the conventional folding can be alternately deformed and fixed.

[0003]

In the conventional folding bicycle, in order to make the folded shape smaller, the diameter of the wheels and the distance between the wheels are made smaller. Compared to non-foldable bicycles, the position of each device has changed, making it difficult to ride and unstable driving, and in the folded state, the shape of the handle and frame is an irregular shape and the wheels etc. are exposed. , It was inconvenient to handle and carry.

Further, what is common to these is that the pedal shaft and the rear wheel shaft are fixed by a chain stay and serve as a basic block when folding, whereas the front wheel and the handle are moved and folded. Is. That is, the pedal device and the rear wheel device are integrated, which restricts the folding method and adversely affects riding comfort and safe driving.

[0005]

In order to solve the above problems, according to the present invention, as shown in FIG. 1, a panel having a size capable of accommodating a chain, a rear wheel, a front wheel, a handle and a saddle when folded is provided. A panel-shaped frame that uses two frame-shaped frames, a chain that is movably connected by a rotating shaft or hinge, rear wheels, front wheels, a handle, a saddle, etc. are arranged. It was constructed as a folding bicycle that can be moved to and fixed in place and stored and fixed inside for storage.

Further, a chain drive, a transmission device, a rear wheel device, a front wheel device, a handle device and a saddle device for constructing the folding bicycle shown in FIGS.
The fixing mechanism shown in FIG. 9 and the storage device for storing the folding bicycle by the panel frame device as shown in FIG.

[0007]

The above-mentioned structure is established, and each of them has the following functions and structures and has its characteristics.

As shown in FIG. 1, when folding, each wheel, handle, and saddle can be housed and fixed between two panel-shaped frames, and when riding, they can be fixed to the outside such as a rotating shaft, a hinge, and an angle. , Etc. are arranged, and each wheel, handle, and saddle move with respect to the panel-shaped frame, thereby constructing a mechanism and structure.

At this time, the size of the panel-shaped frame is slightly larger than the size in which the front wheels and the rear wheels are arranged side by side, and the width is
The size is about the width of the rear wheels and the chain wheel attached to it, the brake mechanism, etc., plus the gap for the moving structure and the thickness of the panel frame. That is, the size when folded is almost determined by the size of the constituent wheels, and is a rectangular thin box shape.

Further, the distance between the wheels when moving, the steering wheel,
The position of the saddle etc. does not depend on the size when folded because it is a structure that can be determined by the length of each fork, arm, post, position of each axis, angle, etc. As a result, the folding bicycle can be configured in a position close to that of a standard non-folding type bicycle that is used to riding, and thus a folding bicycle can be configured in consideration of riding comfort and safe driving.
